Several interactive laboratories have been developedand assessed in undergraduate courses. In addition to containing basic signal processingfunctions such as sampling, convolution, digital filter design and spectral analysis, J-DSP is alsosupported by several toolboxes. An iOS version of the software has also been developed andpresented 13-15. Here, we describe an Android based graphical application, A-JDSP, for signalprocessing simulation. The proposed tool has the potential to enhance DSP education bysupporting both educators and students alike to teach and learn digital signal

decade there has been a significant amount of instructional research anddevelopment in the teaching of physics at the introductory level1-10. This work has demonstratedthat the capability to rapidly acquire and display data provides a valuable tool to promote studentexperimentation and understanding. As a result a number of computer oriented educationalpackages that are directed toward the introductory physics laboratory experience have beendeveloped.11-13Rather than adopt one of these packages we decided to employ LabVIEW, a commerciallyoriented data acquisition environment, in the computerization of our laboratory. This decisionwas motivated by a number of factors which we wanted our computing environment shouldprovide. Among these were

educational methods as “problem-based.”That is, learning how to solve problems is not the same as Problem-Based Learning.Indeed, many engineering programs have introduced “industrial” or “good engineering”practices into their laboratories. For example, the University of Missouri’s ChemicalEngineering department felt that their laboratory courses should encourage students to getresults while also teaching them to write concise reports. In short, lab should not onlydemonstrate theory. As a result, they replaced simple theory-based goals with “practical,industrial problems.”iii Although this change incorporated many of the ideas of the PBLapproach, it is learning through problem solving that defines PBL. This approach notonly allows important knowledge

The commitment to sign a form describing the individual contributions to thereport seems to foster the individual accountability and assigned efforts. Future efforts shouldfocus on comparing different peer-assessment tools during the same semester to evaluate theefficacy of each tool.

chemical engineering curricula in line with professionalconcerns [1], many laboratory experiments have remained relatively unchanged. One reason forthis is the high cost of laboratory equipment that prevents most departments from purchasingnew equipment unless necessary. As much of the laboratory equipment is fixable by replacingparts, it is not uncommon for teaching laboratories to have the same equipment for decades. Forexample, in one of our study sites, the valve used for an experiment on level control on a watertank is being replaced, which is not an uncommon occurrence. However, that particular valvewas manufactured in 1947 and has been used on that exact experiment since 1952 (Figure 2).Likewise, a set of packed-bed columns have been used
